Real Madrid coach Zinedine Zidane has defended Thibaut Courtois.
Courtois was withdrawn at half-time with Real trailing 2-0 against Club Bruges in midweek, and the club later said the Belgian had been suffering from gastroenteritis - rather than an anxiety attack as claimed in the Spanish media.
Courtois was jeered by members of the home support during the 2-2 Champions League draw.
On Courtois, Zidane said: "Regardless of whether it's fair or not, it is what it is. He's strong and is aware of the situation. The first-half performance the other day was down to everyone.
"The important thing is how he's feeling. He's not the only one who was responsible for that first half against Bruges. At Real Madrid you're not allowed to make any mistakes, we can never concede and always have to score. Whenever that doesn't happen, bad things are always going to be said about Real Madrid. We always have to give our all.
"Nobody is a guaranteed starter, not Courtois or anybody else. I never said that. I'm going to use all of them."
